Cant get the *Bling* on my CPU wid Lapping

surely cleaning it off defeats the point?

The Brasso gives the shine/ bling factor to the CPU even after it is cleaned using IA. The shine bling factor is still present. The IA removes the excess/ dirty Brasso. If it is oil based that would be removed by the IA as well.
 
Brasso as Phnom_Penh points out is an mild solvent and a mild abrasive

Brasso is Liquid Metal Polish For Use On Brass Copper Pewter And Chrome.

It is also available as wadding

"Brasso is one of the most widely-used and well-known metal polishes in the world. It is a light brown, opaque liquid which smells of ammonia (the label of Australian Brasso claims "Liquid Hydrocarbons 630g/L; Ammonia 5g/L).

Brasso is also used to polish CDs, DVDs and other optical discs in order to repair scratches. It is a mild solvent and a mild abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and center), it can smooth scratches and reduce their effect. Although the effect is invisible to the naked eye (and often makes the surface look more opaque), it can tremendously improve the ability of many disc drives to read the disc".

I see. So i gues as long as he used something like that he would be fine. Wonder what he did use.

cant say id really be bothered in doing that or lapping unless the temperatures were real bad.
 
Done with 2000 grit I believe:-

havent used any polish :)

soooo gonna give it another go with just dry paper


I want *** Bling ***

This has turned into another willy waving thread :D

Wrong. While the difference is not hugely significant, the shinier it is, the less surface variation there is, therefore meaning more contact (but of course, you actually have to use an abrasive).

Made me giggle, sorry, but shiny really doesn't mean flat - I've got some ball-bearings here if you'd like me to explain more ;)
 
Hes not talking about ball bearing.. and infact he is correct.... the surface of the ball bearing is *smooth* ... would be a better word ;)
 
If you are going to go for a mirror finnish dont use dry paper, otherwise the particles of copper that come off the cpu, will stay on the grit paper, and you will just be rubbing the cpu into them, which will cause scratches and such, thus not leaving a decent finish. you can only go so far with dry before the quality of the finish just wont improve due to the material being taken off scratching the material still on.
 
thats the whole point isnt it ? , to get rid of the concaveness and make it flatter

you could completely mess up the lapping using a curved surface for example and make the top of the cpu look wave shaped but it would still be shiny , going by your logic that means it would be flat

You lap to remove the flaws from the surfaces of both the heatsink and the cpu so that they make better contact. It can be the case where the surfaces aren't topographically flat, but why would anyone be using sandpaper finer than 80 grit if all they wanted to do was stop it being concave?

no you lap to make things flat which is what creates the better contact , if you make it flat enough youl should theoretically be able to wring the cpu to the cooler although i dont think people take it that far with cpus

you could get rid of the surface imperfections and make it look shiny or "bling" with a bottle of T cut/brasso a rag and some elbow grease...it wouldnt be flat though... and

its only the flatness=shininess comment i was getting at , same as the other guy
